Objective To study the distribution of glycosylated hemoglobin A1c (HbA1c) levels in Xiamen,and to investigate the relationship among HbA1c level and gender and age.Methods This was a cross-sectional study.10 487 cases of physical examination individuals in Zhongshan hospital from January 2013 to April 2014 were recruited.HbA1c was measured by ARKRAY HA-8180 automatic glycosylated hemoglobin analyzer (Japan).All data were collected for analyzing the HbA1c levels in different sex and age groups,exploring the rule between HbA1c and age,and comparing the different diagnostic criteria of diabetes mellitus(DM).Differences between the two groups were compared using the Independent Samples T Test.The measurement data of multiple group were compared with single factor analysis of variance (One way ANOVA),and the comparison between two groups was performed with LSD T test.Correlation between different variables was analyzed by Pearson correlation and linear regression.Results Focused on all the 10 487 cases and 9 436 cases with HbA1c ＜ 6.5％ physical examination population,the levels of HbA1c were positively correlated with age,the linear regression equations were HbA1c (％) =0.021 2 × age (years) + 4.811 9 (r =0.348 9,P=0.000) and HbA1c(％) =0.010 9 × age (years) + 5.0944 (r=0.4257,P =0.000)respectively; HbA1c levels in male physical examination population were significantly higher than those in females (P ＜ 0.001),moreover,in different gender groups,HbA1c level had gradually risen with increasing age.Patients at risk for diabetes (prediabetes,39.60％) diagnosed by the criteria of 2010 American Diabetes Association (ADA) were 2.55 times more than those diagnosed by the criteria of international expert committee (15.55％).Conclusions The HbA1c level is related to age and gender in Xiamen city.It is necessary to establish different reference intervals and DM diagnostic cut-off point.The criteria of 2010 ADA can identify more high-risk DM individuals,with is especially suitable for the physical examination screening.

Objective To study clinical feature and therapeutic choice of pituitary adenomas. Methods The clinical data of 239 cases of pituitary adenomas were analyzed. Results Total 93 male and 146 female cases were recruited. The average age was (43.8 ± 14.9 ) years old (3.9-77 years). Prolactinomas were the most common pituitary adenomas (26.8%) , 179 patients (74.9%) underwent surgery, of which 108 (60.3%) with transsphenoidal approach and 71 (39.7%) transcranial approach. The other 60 cases were treated nonsurgically. Conclusions Pituitary adenomas may present hormonal abnormalities or neurological symptoms.Some adenomas were accidently detected by MRI. Prolactinomas were the most common pituitary adenomas.

Objective To explore the sensitivity and accuracy of directly sequenced core and non-structrural protein (NS)5B regions for hepatitis C virus (HCV)genotyping.Methods Fifty-one serum samples from chronic hepatitis C patients were collected in the study.Reverse transcription-polymerase chain reaction was used to amplify core and NS5B regions.Genotypes or subtypes were determined by the phylogenetic analysis of directly sequenced core and NS5B regions.Results Among the 51 samples,49 (96.1 %)were successfully typed by phylogenetic analysis of directly sequenced core region.There were overall five genotypes determined in the area,including 1b (61 .2%,30/49 ),2a (20.4%,10/49 ),2b (2.0%,1/49),3a (4.1 %,2/49 )and 6a (12.2%,6/49 ).The positive rate of HCV genotying was 88.2% (45/51 )on the basis of NS5B region.HCV genotypes 1b,2a,2b,3a and 6a were found in 62.2% (28/45),20.0% (9/45 ),2.2% (1/45 ),4.4% (2/45 )and 11 .1 % (5/45 )of the patients, respectively.Conclusion The HCV genotyping based on core regions,compared with that based on NS5B,shows the advantages of primer design,amplification efficiency and accuracy,suggesting that it has the priority to be used in the epidemiological and clinical study of HCV genotyping.

Objective:To evaluate the efficacy and safety of elbasvir/grazoprevir (EBR/GZR) in patients with genotype 1 chronic hepatitis C in the real-world.Methods:This was an open-label, single-center, retrospective real-world study. A total of 103 genotype 1 chronic hepatitis C patients who were treated with EBR/GZR in Henan Provincial People′s Hospital from May 2018 to October 2019 were enrolled.And the clinical baseline characteristics of patients and the effectiveness and safety of antiviral therapy were respectively evaluated.Results:A total of 103 patients were enrolled in the study with an age of (47.6±13.9) years. Fifty-five (53.4%) patients were male and 48(46.6%) were female. One point nine percent (2/103) patients were genotype 1a hepatitis C and 98.1%(101/103) were genotype 1b hepatitis C. Seventeen genotype 1b hepatitis C patients were previously treated with interferon, and three patients co-infected with hepatitis B virus (HBV). Among the 103 cases, 35 had underlying diseases and 26 had combined medication. Ninty-eight cases completed 12-week treatment and 89 cases completed 12-week follow-up after treatment.Overall, 89 cases achieved sustained virological response. The overall incidence of adverse reactions was 20.4%(21/103), and the main adverse reactions were fatigue, insomnia and anxiety. No serious adverse event occurred. The three patients with HBV co-infection had no hepatitis B activation after treatment.Conclusion:EBR/GZR is effective and safe in the patients with genotype 1 chronic hepatitis C in China.

Objective To analyze hepatitis C virus genotype(HCV GT)1b NS5A resistance-associated variants(RAV)and its related factors,and to provide references for direct-acting antivirals (DAA)agent selection and application.Methods From January 2017 to July 2017,53 hepatitis C patients were selected from the Department of Infectious Diseases of Henan Province People's Hospital. The mutations of L31M and Y93H in NS5A RAV were analyzed in 43 HCV GT1b patients,and their correlations with hepatitis C virus,liver function,platelet and liver fibrosis diagnostic model[APRI, gamma-glutamyl transpeptidase to platelet ratio(GPR),FIb-4]were analyzed.The quantitative data were compared by two independent samples t test,and the qualitative data were compared by chi square test. Results Fifty-three subjects were enrolled,including 43 GT1b(9 males and 34 females)and 10 GT2a(2 males and 8 females).No other genotype was detected.The incidence of NS5A RAV in 43 HCV GT1b patients was 13.9%(6/43),of which L31M and Y93H were 1/43(2.3%)and 5/43(11.6%)with no significant difference(χ2= 1.500,P= 0.219).There were no significant differences in HCV RNA, ALT,AST,albumin,platelets and age between patients with or without mutation(all P> 0.05). Conclusions The incidence of NS5A RAV in HCV GT1b patients is high,but not affected by virus, biochemical factors and liver fibrosis.The detection of NS5A RAV before HCV treatment is helpful for rational selection of DAA,which could reduce the drug resistance.
